AcedGrDraw and zooming

[majklha]

I use AcedGrDraw function to highliting or showing selected line or nearest point.

And this temporary entities hide always, when user zooms. It is clear, of course, because Autocad is redrawing view during zooming. 

But what to do, if I want to let visible temporary lines during zooming?

maybe Transient graphics and AcGiTransientManager
